One of the great joys of prohibition-era gangster films is the colorful dialogue spat out by the likes of James Cagney and Edward G. Robinson. As that element would, obviously, be missing from a silent film, I wasn't sure how I would react to Underworld.
Not to worry. This is a great film, one of the best prohibition-era gangster films I've seen, ranking slightly ahead of Little Caesar and the Public Enemy, and maybe only slightly below Scarface (1932). Tough, tense, tightly written--interestingly, Howard Hawks is credited for the scenario--and with gorgeous DARK cinematography and Josef von Sternberg's usual excellence in direction. I barely missed the lack of gangster-speak.
I suppose this film was a template upon which a lot of gangster films were based. It struck me while watching it how much it had in common with the Coen brothers' Miller's Crossing (1990)--a love triangle between a mob boss, his moll, and his right hand man. And it's all about the gangsters' peculiar code of ethics.
I'd rate it a perfect 10, but for a muddled and badly-handled prison break sequence, which I watched three times and still couldn't figure out. Maybe I'm just dense; maybe it was actually a genius bit of filmmaking and it just flew over my head, but for now, 9/10.
